and Quararibea. ‘These, however, are not of a fundamen- 
tal character, and he names three species, now referred 
to Matisia, which are inseparable from Quararibea on the 
basis of wood structure alone. Record and Hess (Tim- 
bers of the New World (1943) 96) have maintained the 
two genera as distinct. 
In consideration of the differences in structure of the 
ovary, of the absence of the characteristic odor of Quara- 
ribea, and of the presence of minor and variable vegeta- 
tive differences, I believe that Matisia is best main- 
tained as a distinct genus.
